Q: My water is crystal clear but I have a "wet socks" odor I cannot get rid of.

A: 2 tablespoons of non-chlorine shock should take the odor away but keeping it away.
pH is too low (below 6.5)
Copper is too high (above .7ppm)
Filters are dirty

PROCEDURE TO SOAK/CLEAN FILTERS
Mix 2 Parts water, 1 Part Muriatic Acid in a tall kitchen bag.
Add 2 tablespoons of TSP (trisodium phosphate).
Soak 15 minutes to 12 hours, rinse off with cold water.
